For those of you who want to fix WotL's slowdown without messing with files on your PSP or don't want FFT: KO's changes, I've created a .ppf file with just the slowdown fix. Just patch your WotL ISO with the .ppf using PPF-o-Matic, and the slowdown will be fixed. You can find that .ppf file here. Enjoy!

"You, no less human than we? Ha! Now there's a beastly thought. You've been less than we from the moment your baseborn father fell upon your mother in whatever gutter saw you sired! You've been chattel since you came into the world drenched in common blood!"
